irsim: error: expected a platform name, e.g., 'macosx'

[gkottar@…]

I can not install irsim under OS X Yosemite. I am using Xcode version Version 6.1.1 (6A2008a).

Quoting what is printed on the screen:

Staging irsim into destroot
Error: org.macports.destroot for port irsim returned: command execution failed

The real error seems to be:

/usr/include/sys/stdio.h:39:52: error: expected a platform name, e.g., 'macosx'

The log is difficult to read because this error occurs repeatedly, and because a parallel build is happening, the multiple error messages are being interleaved. The build system then fails to recognize that the build has failed, and proceeds anyway to the destroot phase, which repeats the failing build.

I can reproduce this problem on my Yosemite system, even with a serial build. The error I see is:

/usr/include/sys/stdio.h:39:80: error: expected a platform name, e.g., 'macosx'
int renameat(int, const char *, int, const char *) __attribute__((availability(1,introduced=10.10)));
                                                                               ^

This is now sounding familiar. OS X's headers use defines like 'macosx' and 'ios', but irsim's build redefines 'macosx' to '1' which breaks everything. We encountered this two years ago in #36250 and thought we fixed it...

Ah, I see: we applied the patch only on OS X 10.8. We should have applied the patch on OS X 10.8 and later.

Fixed in r131282.

And this patch was integrated into irsim 9.7.78. I updated irsum to 9.7.87 in r131283.
